Should monsters that EAT_FOOD suffer from the effects of that food

Not sure if it is worth the coding effort however, There are 4 current creatures that attack with EAT_FOOD. I would think that it is possible that those creatures could suffer the same beneficial or adverse effects of a mushroom when they eat it, thus if they ate a mushroom of cure serious wounds they get healed some, and if they eat one of poison they suffer the damage and effects associated to it.

Though eating the food item might be enough of a damage to the character.
